基于rtmp+nginx 、vlc实现FFmpeg推流与wpf端拉流

这周在研究基于rtmp+nginx直播流的实现，现总结如下：

1.nginx部署

1.1将nginx_1.7.11.3_Gryphon.zip解压，启动nginx.bat文件移动至nginx_1.7.11.3_Gryphon解压后文件夹内，双击bat,启动nginx

1.2浏览器输入：http://localhost:1234/ 若出现如下页面，恭喜你部署成功！如未出现，可能是防火墙或者端口被占用，可修改nginx_1.7.11.3_Gryphon\conf\nginx-win-rtmp.conf中的端口号。

2.FFmpeg推流至服务器

2.1推流命令示例：打开cmd,cd到nginx_1.7.11.3_Gryphon路径下 输入 ffmpeg -re -i 11.mp4 -vcodec libx264 -acodec aac -f flv rtmp://127.0.0.1:1935/live/home 并回车 。rtmp://127.0.0.1:1935/live为推流应用，home为具体流的名称，值随意，如需多个推流同时进行，只需更改home，如rtmp://127.0.0.1:1935/live/test

3.WPF端集成vlc拉流

3.1  项目里先添加Vlc.DotNet.Core.dll，Vlc.DotNet.Core.Interops.dll，Vlc.DotNet.Wpf.dll，可直接用我的 .net4.0版本，亦可下载源码自己编译（https://github.com/ZeBobo5/Vlc.DotNet   需用vs2017及以上编译）并在xaml中添加xmlns:local="clr-namespace:Vlc.DotNet.Wpf;assembly=Vlc.DotNet.Wpf"引用，将libvlc解压至wpf生成路径下，libvlc包含必须的解码库文件及插件

59             System.Diagnostics.Debug.WriteLine(message);
